After Odysseus and Circe leave the island where they have traversed the labyrinth, distant shots of the boat show the sail unfurled, while close-ups show it rolled up.
Odysseus told Circe his city Ithaca was far more modest than Troy, lacking even a city wall. Yet the town shown later on has a wall.
It was not Agamemnon, king of Mycenae, but his brother Menelaus, king of Sparta, who married Helen. Although all men who had courted Helen were pledged to fight to aid Menelaus in recovering her from Troy, Agamemnon led the troops because he was the elder and stronger brother.
Agamemnon scoffs at Achilles' suggestion that he join his men in assailing Troy's gate, because Agamemnon is a king and above such things. Yet Achilles was also a king, as were many of the heroes known from Homer's tales of the war.
According to mythic tradition, Achilles was already long dead before Odysseus had the idea for the Trojan Horse.
Odysseus makes a deal with Agamemnon that if he thinks up a ploy to penetrate Troy's walls, Agamemnon will never force him to war again. Yet Agamemnon had no power to force Odysseus, himself a king of an independent region of Greece, to war. Odysseus and the other leaders like Achilles had sought to marry Helen, and to prevent war between them all pledged to leave her chosen husband in peace and fight anyone who tried to harm the couple. When Paris abducted Helen, her husband invoked the agreement and went to war.
A zipper is visible in some of Penelope's costumes, an invention of the early 20th century.
The boat Odysseus attempt to sail home to Ithaca on is laughably small. It is more of a dinghy he might use to take him to a waiting warship anchored offshore than a vessel that could conceivably survive the sea.
After Odysseus leaves Troy, action cuts forward to when his men had been "searching these seas for months," in the words of one of the crew. It is odd that the group has waited so long to have the following conversation about how the boat seems to be under a curse and not getting anywhere, and for Odysseus to ask his prisoner Circe her name and ask if she has any knowledge of where to find land.
A large electrical transformer is briefly visible in the background around the 39:55 mark.
Everyone on the boat with Odysseus follows after him to the islands as he swims away under the influence of the Sirens' song, yet instead of simply sailing or rowing the boat to the island, they all swim and leave the boat to float away.
The Greeks' ruse with the Trojan Horse involved them removing their ships from sight to trick the Trojans into thinking they'd fled, then returning at dark. Yet when Odysseus attempts to leave after the city's fall, there is not a single other vessel in the bay.
When Circe introduces herself to Odysseus on the boat, she mispronounces her name as "Circes."
